That's not too big of a deal now that we know there is a stock adapter for the XCR to fit the ACR's stock, and most other accessories can be screwed onto its keymod slots like anything else out there. I must be insensitive to it or too new to this but I'm fine with the trigger as-is even in a competitive match setting. A binary trigger would be fun and if you have machining skills, I don't see why it won't be possible to make one. I just don't understand how the binary trigger is able to force the hammer to strike again on the back pull of the trigger (it would help if I had one to examine). The XCR's hammer looks just like that of an AR-15's but I'm not sure of any of the differences outside of it.Too small of a market share to have aftermarket support.
Just sent an email. Surprised how inexpensive their lowers are frankly.Rumor the forum, Alex wanted a shorter lower. It would have to have been about .25" taller to work with an AR trigger. I think someone squeezed in a cmc(?) trigger into a xcr way back but it took some machining. I haven't looked in a long time but I thought the layout/spacing on the pins and safety were pretty close to the AR pattern. Larger barrel on the xcr safety.
FWIW, I asked lingleindustries.com about a custom lower with AR fcg, built in 1913 stock adapter in AR and AK mag versions. He said I wasn't the first to ask. They're just getting started and they aren't a FFL yet. Send them some messages TY let them know there's interest.
Yeah, mixed bag. OTOH, serialized upper would be cool....for lower swaps....but I've swapped a fair amount of uppers (from railed to KM to competition, to mini and standard). It would be better if we just didn't have NICS at all.Just looked at their offerings. Make me wish RA had serialized the upper instead. AK/STANAG lower swaps would be so awesome.
Interesting idea, actually. You think the dimensions on the upper would change much if they serialized it? Are we on the 3rd revision of the XCR right now? Maybe the next revision they could serialize both the upper and lower, so that if you don't get a complete rifle from RA, you could build around it with their parts. A shorter lower ought to be an advantage for some AR-15 builders, and having unified uppers are a premium AR product - it's sure to be competitive when LMT has got it hands busy.Make me wish RA had serialized the upper instead. AK/STANAG lower swaps would be so awesome.
Fascinating. With luck, it's possible that all you would need to do is CNC machine a hammer that's compatible with the XCR and drop it into the binary trigger. I really need to examine a binary trigger though, because I don't know if there is something about the hammer in it that helps with the binary fire function. I think I'll get one just to examine when my budget is able to breathe.I think someone squeezed in a cmc(?) trigger into a xcr way back but it took some machining.

Right, so before Sean or someone jumps down my throat about this, I took a closer look at the trigger group in the XCR last night and noticed that it is COMPLETELY different from from the AR-15 trigger or just about any other trigger group I can find. Among other things, the disconnector stops the hammer using a kind of c-shaped hook that grabs into a peg on the side of the hammer. There is nothing in the Frankin Armory catalog or anything in the aftermarket like it. I can only imagine the kind of time and R&D that was needed just it make this thing.Has anyone created an after market or tried to install a Binary trigger on their XCR?
It's hard to tell when I don't have an AR lower to compare and the schematic on the Robinson site is outdated and does not show the trigger that is being used for the 2018 models. Do you know an updated one? Perhaps with dimensions etc?How do the pins and safety line up relative to an AR?
Not sure why you chose to call me out specifically, but hey, whatever. You basically invited the following response by singling me out, so here it is:Right, so before Sean or someone jumps down my throat about this,
